Introduction Introduction (LSI Quadrant I): SAY: The Central Processing Unit (CPU) chip processes instructions, performs calculations, and manages the flow of information through a computer system. ASK: Does anyone know what part of the human body the CPU is like? (the brain, because the brain processes instructions, performs calculations, and manages the flow of information through the body) SAY: There are several factors that should be considered when selecting a 2

3 CPU, such as the manufacturer, speed, socket types, and fans. We will go over these factors in further detail. Outline Outline (LSI Quadrant II): Instructor Notes: I. CPU a. How it works II. III. Attributes used to rate CPUs Types of CPUs a. Intel b. AMD c. Cyrix Note: Instructors can use the PowerPoint slides, handouts, and note pages in conjunction with the following outline. IV. Cooling Fans V. Heat sinks VI. Memory buses VII. System Clock VIII. Multiprocessing IX. Choosing a CPU a. Manufacturer b. Speed c. Socket Type d. Fans Application Guided Practice (LSI Quadrant III): 1. The teacher demonstrates each lab principle. 2. The teacher maintains direct supervision in the lab, providing guidance when warranted. Independent Practice (LSI Quadrant III): 1. Students work individually on lab assignments, demonstrating their skills in identifying and discussing the various lab requirements and results. Summary Review (LSI Quadrants I and IV): Checking for understanding (Q&A Session) Q: How does a CPU work? 3

4 A: Input/Output (I/O) unit manages data and instructions entering and leaving the CPU Arithmetic Logic Units (ALUs) do all comparisons and calculations Control unit manages all activities inside the CPU itself Q: Who are some of the more common manufacturers of CPUs? A: Intel, AMD, Cyrix. Q: What is the main function of the heat sink? A: To pull heat away from the CPU. Q: What are some of the considerations when purchasing a CPU? A: Manufacturer, speed, socket type, fans. Evaluation Informal Assessment (LSI Quadrant III): Monitor student progress during independent practice, and provide independent reteach/redirection as needed. Formal Assessment (LSI Quadrant III, IV): Use the CPU Exam and Exam Key. Extension Extension/Enrichment (LSI Quadrant IV): Students that have mastered the lab assignments can peer-tutor students (one-onone) that are having difficulty with the lab. 4
